A high-profile attorney is calling for Rush Limbaugh to be prosecuted on a defamation charge, saying an obscure Florida law can be used to punish him for calling a college student a ----and a --------- on the air.

Gloria Allred, the famed celebrity lawyer, sent a letter to the Palm Beach County Attorney’s Office on Thursday saying prosecutors should consider a charge under an 1883 law making it a misdemeanor to question a woman’s chastity.

“He has personally targeted her and vilified her, and he should have to bear the consequences of his extremely outrageous, tasteless and damaging conduct,’’ Allred said in a phone interview Friday.

We asked Nielsen to calculate how much ad money is spent on Limbaugh's show. The audience ratings and adspend monitor doesn't measure show-level spending, but it was able to tell us how much money each advertiser spent on radio overall last year: $363 million.

Over at the left-wing Politico, the headline is "Limbaugh Boycott Cost 'Millions." But once you actually click on the story, you get the real story:

"It hit us pretty hard," Dickey said during a call with financial analysts yesterday. "A couple of million bucks in the first quarter and a couple of million bucks in quarter two."

Dickey would not give exact figures, but said the "millions" accounted for "about one percent" of the roughly $245 million in first quarter revenues, and said he expected revenue to return to normal in June.

Cumulus owns just 38 of the 600 stations that air the Rush Limbaugh Show, which is nationally syndicated by Cumulus's competitor, Clear Channel Media. For its part, Clear Channel saw total revenues increase 6 percent the first quarter of 2011 to $671.5 million in the first quarter of 2012, according to MediaPost.

You have to wonder how much this failed boycott cost the suckers who contribute money to the anti-Semitic, Soros-funded, tax exempt Media Matters who led the campaign.

In other news: during this failed boycott, Limbaugh's ratings have increased across his 600 stations while CNN's ratings have collapsed, and the Washington Post is sinking almost as fast.
